I have an three phase images, in which lighter color represents Nickel, darker shade YSZ and complete black is pore area. After tresholding, I formed a binary image for each phase. Now my question is : 1) how to combine all these three binary images into 1 image ? 2) how to calculate interface area between two phases for example Nickel(while) and YSZ (darker shade) ? I know if I can find the Interphase length then by using stereology techniques I can count the no of intersection points of test grid line with interphase line and can calculate interphase area. But I dont know how to find the Interphase length in this image ?? Images are attached for your reference.

You've probably figured this out by now, but you use the gray level cooccurrence matrix, done by the gracomatrix() function in the Image Processing Toolbox.

Hi, No I am not able to figure out this till now. I looked into graycomatrix, I didnt find much help there. Can you be bit more specific like how to find tow phase boundary and triple phase points in a 3-phase image. It will be great help if you can give more specific answer or the resources where I can look into this.

The GLCM tells you how many pixels of one intensity are adjacent to each of the other intensities. Why would this not help?
Why do you think you need to get phase boundaries? Just for visiualization? Where would the boundary go? Over pixels of which phase?
